Patent EP-0044184-A3 (EP)
IPC: C08L81/00
Filed: 1981-07-06
Abstract: A polymer blend which is capable of exhibiting an 
anisotropic melt phase, improved processability characteris­
tics and the ability to form molded articles having satisfac­
tory mechanical properties is provided. The polymer blend 
comprises approximately 5 to approximately 95 percent by 
weight, based upon the total weight of the blend, of a 
polyarylene sulfide and approximately 5 to approximately 95 
percent by weight, based upon the total weight of the blend, 
of a melt processable wholly aromatic polyester which is 
capable of forming an anisotropic melt phase apart from the 
blend. Blend compositions containing high concentrations of 
wholly aromatic polyester (i.e., at least 60 percent by weight 
wholly aromatic polyester) can be used to form fibers and 
films.
Patent EP-0056546-A3 (EP)
IPC: H04B3/23
Filed: 1981-12-21
Abstract: A digital adaptive finite impulse response (AFIR) filter 
having a large number of coefficients is composed of two or 
more separate filter units. The first filter unit computes 
response samples h₀ - h n+1  in response to input signal 
samples to provide a partial estimated response during each 
sampling period. After the signal samples are fully processed 
by the first unit, they are transferred to a second filter unit 
which produces response samples h n+2  - h p+1  in response 
thereto to provide a second partial response. The sum of the 
two partial responses is computed to provide the total 
estimated system response. The two independent filter units 
thus act simultaneously to provide twice as many coeffi­
cients as prior art AFIR filters in the same amount of time.

Title: Device for splitting round wood
IPC: B27B25/04
Filed: 1983-03-01
Abstract: A device for severing round timber includes a rotatable circular saw and a transversal feeding device feeding round timber pieces towards the saw and for feeding cut sections of the timber from the saw towards the discharge end of the device. The feeding device includes a number of rotary conveying chains arranged in groups in the feeding direction at one side of the saw and at the opposite side of the saw. The conveying chains of two groups extend in the feeding direction such that they include an acute angle with each other and diverge from one another whereby timber sections cut off by the saw tend to move away from each other and, after being cut off, do not contact the saw teeth in the area of the saw blade.

indicator through the lid. The disc 220 may have a foam layer 
under the indicator for compensating for manufacturing 
tolerances.

Abstract: A photosensitive material containing a hydrophilic pig­
ment is exposed to light to form a pigment pattern defining 
a particular image. The photosensitive material is brought 
into intimate contact with an image receiving material 
having a pigment fixing layer. The mutually contacting mate­

IPC: F24D12/02
Filed: 1984-04-26
Abstract: The thermal efficiency of a boiler is increased by actively 
causing condensation of water vapour in the flame gas and 
transferring the latent heat of condensation to water being fed 
to the boiler. A heat pump system incorporating an 
evaporator (32) and a condensor (30) is used to provide a 
controllable heat sink which causes the active condensation. 
The condensor (30) is preferably included in a heat exchanger 
(20) so that the water being fed to the boiler is heat by both the 
flame gases from the boiler and by the condensor.

Title: A mirror wafer of compound semiconductor
IPC: H01L21/02
Filed: 1985-01-24
Abstract: Compound semiconductors belonging to groups III-V have 
a crystalline structure of the zinc blende type. Wafers sliced 
from a single crystal ingot on {100} planes have four cleavage 
planes. Two parallel cleavage planes are equivalent. But two 
cleavage planes perpendicular with each other are unequiva­
lent. The etching speeds on the unequivalent cleavage planes 
are different from some pertinent etchant.  
     A difference of the mesa direction and the reverse-mesa di­
rection along unequivalent cleavage planes exists in compound 
semiconductors unlike silicon semiconductor.  
     By etching process using a pertinent etchant natural aniso­
tropic patterns appear on the rear side on a wafer to denote the 
mesa direction on the front surface by nature. Natural pat­
terns have generally elongate shapes parallel with each other, 
resembling lines or ellipsoids. The direction of the longer side 
is the mesa direction on the front surface. Otherwise artificial 
parallel patterns can be formed on the rear surface to denote 
the mesa direction by photoetching process using photoresist 
and a mask with anisotropic pattern. This invention is especial­
ly useful for rectangular or square wafers which have not orien­
tation flats on the peripheries.

Title: Concentrating immunochemical test strip
IPC: A61K39/00
Filed: 1986-02-13
Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.
